Introduction
In this article, I will explain about checking the atmospheric pressure by using
Arduino
Mega 2560.
It can correctly give the range of pressure in the serial monitor.
Parts Of List
Arduino mega2560
MPX4115A
Dual power supply
LM741
Bread Board
potentiometer
MPx4115A
It can correctly give the air pressure in the atmosphere.
It can be a barometer application.
